you are correct.

What I am saying is that hiding spice's default with adding
diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c
index 27fcdf1..67b9e2a 100644
--- a/src/conf/domain_conf.c
+++ b/src/conf/domain_conf.c
@@ -1798,6 +1798,9 @@ virDomainVideoDefaultRAM(virDomainDefPtr def,

return 4 * 1024;
+ case VIR_DOMAIN_VIDEO_TYPE_QXL:

}
seems suboptimal to me.
